We look at the division of 77447153 by 503 
We want to figure out the number of times 77447153 can be divided by 503.

Step 1:
The number 503 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 503

Moving on to step 2:
If we divide 77 by 503, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 503

Step 3:
When dividing 774 by 503, we get 1 with a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 503 from 774 to get 271.
Bring next digit (4) of the dividend behind the 271 and repeat the process: 2714 / 503

Moving on to step 4:
2714 divided by 503 is 5 with a remainder of 199.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2515 from 2714 and we're left with 199.
Append the next digit (7) from the dividend to 199 and continue with: 1997 / 503

Going ahead to step 5:
When dividing 1997 by 503, we get 3 with a remainder of 488.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we subtract 1509 from 1997, we get 488.
Fetch the next digit (1) from the dividend, attach it to 488 and continue: 4881 / 503

Going ahead to step 6:
503 can be fit into 4881 9 times, resulting in a remainder of 354.
Put 9 as the next digit of the answer. 
Result so far: 1539.0
The remainder is 354 after subtracting 4527 from 4881.
Append the next digit (5) from the dividend to 354 and continue with: 3545 / 503

Step 7:
If we divide 3545 by 503, we get 7 and a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 15397.0
Subtract 3521 from 3545 to get 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 503

On to step 8:
The number 503 fits into 243 0 times, leaving a remainder of 243.
Write down 0 as next digit of the result. 
Result so far: 153970.0
Subtracting 0 from 243 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 9:
The number 503 fits into 2430 4 times, leaving a remainder of 418.
The next digit of our result is 4. 
Result so far: 153970.4
Subtracting 2012 from 2430 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 10:
When dividing 4180 by 503, we get 8 with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 153970.48
If we subtract 4024 from 4180, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
When dividing 1560 by 503, we get 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 153970.483
Deduct 1509 from 1560 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
If we divide 510 by 503, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 153970.4831
If we subtract 503 from 510, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
If we divide 70 by 503, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 153970.4831
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
503 can be fit into 700 1 times, resulting in a remainder of 197.
The next digit of our result is 1. 
Result so far: 153970.483101
If we take 503 away from 700, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 15:
The number 503 fits into 1970 3 times, leaving a remainder of 461.
The next digit of our result is 3. 
Result so far: 153970.4831013
The remainder is 461 after subtracting 1509 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 16:
503 goes into 4610 9 times with a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 153970.48310139
Deduct 4527 from 4610 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Our division results in 153970.48310139 with a remaining 8.3e-08.
